BIPV, i.e. building integrated PV, is a building integrated Photovoltaic, i.e. photo voltaic. BIPV technology is a technology that integrates solar power (photovoltaic) generation products into buildings. With the development of various green buildings and near-zero energy consumption buildings at present, BIPV products meet the market outbreak period, and the application of the BIPV products is also expanded to scenes such as curtain walls, sun-shading boards, platforms, car sheds and the like from an early single roof. In order to further expand the popularization range, the attractiveness of the photovoltaic power station needs to be improved as much as possible on the premise of feasible cost, so that the photovoltaic power station and the building can be more harmonious and attractive. However, the colors of the photovoltaic modules are limited, and the appearance style of the photovoltaic power station and the appearance style of buildings are difficult to be consistent. Therefore, the development of the colorful BIPV solar dual-glass assembly which can integrate the photovoltaic building and is more gorgeous and more aesthetic is necessary.

However, the two color schemes use color chemical dyes, the color development principle is that most of visible light in a wave band is absorbed, light with the color wavelength of the dyes is reflected, the light utilization rate is low, and the glass transmittance of the dyes is 40% -80% (different in color and transmittance), thereby affecting the power generation efficiency of the component. Meanwhile, the chemical dye has poor ultraviolet resistance, and when the chemical dye is used outdoors and exposed to sunlight for a long time, the ultraviolet rays can damage the molecular structure of the dye, so that the color is changed or faded, and the attractiveness of the component is influenced. In addition, pollution is generated in the production process of the chemical dye, and certain pollution is caused to the environment.
